Application led September 18, 1916. Serial No. 120,634.

To all whom t may concern:

Be it known that I, CHARLES E. SHADALL, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain newk and useful Improvements in `Water- Closets, `of which the following is a specification, reference being had to the accompanying drawing, forming a part thereof.

The main objects of this invention are to provide within the structure of a water closet bowl, means for its ventilatlon; to facilitate installation of the Ventilating means with the bowl; to prevent disagreeable noise in the Ventilating connections due to longitudinal vibrations in the air entrain- I ing passage or other causes; to p rovide for varying t e air entraining fluid jet according to varying conditions such as the pressure ofthe fluid supply; to avoid as far as possible exposed metal -parts and joints, which are objectionable; and generally to improve the construction and operation of devices of this class.

It consists in the peculiar construction, arran ement and combination of parts as hereinafter particularly described and pointed out in the claims.

In the accompanying drawing like characters designate the same parts in the several figures. l

Figure lis a vertical section from front to rear of a water closet bowl embodying the invention; Fig. 2 is a vertical section on. an enlarged scale of the aspirator constitutmg a part of the invention; F ig.l 3 is a horizon-v tal section on the line 3--3, Fig. 2, of the aspirator nozzle; Fig. 4 is a cross section on the line 4 4, Fig. 2; and Fig. 5 is an axial section of a modified form of the nozzle. j

Referring to Fig. l, a desi ates a water closet bowl formed around t e top with a flushing rim b, of the usuall or any suitable construction, and in the lower part with a water trapped or sealed outlet passa e and soil pipe connection c. It is provide with a rearwardly projecting housing or extension forming an aspirator chamber and a foul air outlet passage al, which at one end has an air inlet and drain opening into the convenient point `a stem n extending upwardly throughsaid passage are conducted to any and discharged into the atmosphere outside ofthe building in which the closet is installed or discharged into a Ventilating shaft or Hue with which the building is provided.

The wall of the housing or extension forming the aspirator chamber and passageal is formed integrally with the bowl a, and completely surrounds said chamber and passage bteween the air inlet and outlet openings at its inner and out'er ends, thus concealing the aspirator and avoiding exposure to 'view of metal parts except the pipe connections required to operate the aspirator and carry off foul air.

A pipe f connects the flushing rim or passage of the bowl with a iushing tank or other source of water supply, controlled by a valve in the usual or any suitable manner.

To draw foul air and odors from the bowl and' force them out through4 the Ventilating pipe e, an aspiratorVv is provided in the chamber d of the bow .The aspirator may be constructed in va- Arlous ways, one of the preferred forms being gs. 2, 3 and 4. In accordance i shown in Fi with the form illustrated, it comprises a T- shaped casing consisting of a nozzle tube or body It, and a valve case z', which may be formed as shown, integrally therewith, and at rightangles or transversely thereto. The valve case, as shown in the present instance, is formed with a flange j, and provided at its lower open end with a cap nut k, by which the aspirator is secured in an opening formed in the lower wall of the chamber 0l of the bowl, as shown in Fig. 1. A pipe l, for supplying water, steam or other iluid under pressure, to operate the aspirator, is connected with the valve chamber by the cap nut 7c. Au its upper end the valve chamber communicates with the nozzle tube or body z. through a port which is normally closed by a valve m vguided therein and having through the bore of the nozzle tube andprvided at its upper end with a head or guide o, fitted in an opening in the upper side of the nozzle tube. The valve is closed and held normally against its seat in the upper part of the chamber or casez, by a spring p. The nozzle tube or body h, which is supported by the valve case z' within and lengthwise of the chamber (Z, is open at the ends and provided at the end toward the bowl with a screw cap or plug g, and at the opposite end with a tip or cap r, threaded thereon and formed with a jet orifice s, which is directed toward the outlet opening from the chamber d into the Ventilating pipe e.

To vary or adjust the size of the jet issuing from the orifice s, or the amount of fluid passing through the nozzle according to varying conditions, such as widely differ ent pressures of the fluid supply, the nozzle is provided with a flanged thimble t, threaded in the end of the tube or body h to which the tip or cap r is applied. The outer end of the thimble -is split and the tip or cap 1 which fits'over it, is tapered so that by screwing the tip or cap more or less upon the tube or body h, the bore of the thimble. may be contracted more or less as desired.

The nozzle is provided with means 'for imparting a spiral, whirling or rotary movement to the fluid jet issuing from the orifice` s, whereby an even and symmetrical jet is produced, a whirling or spiral movement is imparted to the entrained air, and disagreeable noises resulting from vibrations of the air in the chamber d and pipe e, or from other causes, are prevented. This may be accomplished in different ways, for example,

by'spiral or oblique holes u, formed in a partitlon or cross wall of the tube h between the valve m and the thimble t, as shown in Figs. 2, 3 and 4. j

To prevent clogging or obstruction of the jet orifice s and of the passage through the thimble t, the nozzle is provided with a clearer, consisting of an axially movable rod or wire v,` passing from the jet orifice through the thimble and a central opening in the partition or cross wall of the tube z. and connected at its inner end with a yoke fw, guided in and movable lengthwise of said `tube. The valve stem n, passing through an elongated opening in the yoke w, is provided with an incline ac, which by engagement with the yoke, shifts the rod or wire 'v backward, withdrawing it from the jet ori.- fice s when the valve m is opened, thereby loosening and dislodging any dirt or obstruction which may have been caught in said orifice or in the bore of the thimble t. The clearer rod or wire v is moved in the opposite direction when the valve m is closed, bya spring y, interposed between the cap or plug g and the yoke w.

`The valve m may be opened manually by a handle, or by a connection with the hinged seat z of the bowl, as shown. For this purpose a lever 2, mounted on the nozzle and engaging-lat one end with .the head or guide o on the valve stem, is connected at the other end by a rod 3 passing through an opening in the upper wall of the chamber d with a rearwardly projecting arm 4 on the seat, as shown in Figs. 1 and 2. y

The Ventilating pipe einto which the as pirator nozzle is directed from the chamber d of the bowl, is preferably made of elbowshape and formed at thebend opposite the orifice s with a concave recess or cavity 5, which facilitates separation of water from the air Awhen the aspirator'is supplied with water or steam. The pipe e is formed in the lower side of its horizontal branch with a longitudinal groove or channel 6, through which water caught in the cavity or recess 5, drains back into the chamber al and thence into the bowl.

Referring to Fig. 5, showing a modification of the nozzle, a tapering tip 7" in which the jet orifice sis formed, is screwed into the tubeor body t'of the nozzle and is pro'- vided at its inner end with a plug 7 removably threaded therein 'and formed with spiral or oblique holes u', bywhich a rotary orwhirling movement is imparted to the jet issuing'from the orifice s and to the air entrained by the jet.

In the operation of theappara-tus, when the valve m is opened, water or other fluid under pressure is admitted from the pipe Z to the nozzle and issuing therefrom through the orifice s in a jet or spray, entrains air therewith through the chamber d, thereby' i drawing foul air and odors from the bowl and forcingthem out through the pi'pe c. When water or steam is used to operate the aspirator, the w-ate'r or condensedsteam directed into the cavity 5 at the bend of the Y pipe e, is separated from the air and drains back through the channel 6 in the lower sideof the pipe into thechamber d and thence into the bowl'above the water seal.

A -rotary or whirling movement .is .im-v 7 parted to the water or other fluid under pressure in passing through the spiral o'r oblique holes u or u', thereby causin a rotary or whirling movement of the jet lssuing from-the orifices ors and of the air entrained therewith through thechainber d and adjacent end of the Ventilating rpipe e, tending to produce an even or symmetrical and more effective air entraining jet and preventing the noise resulting from longitudinal vibrations of the air in the Ventilating pipe or from other causes. Y

, With the opening and closing of the valve m the clearing rod or wire v is vshifted Various changes in the details of'construc- Y tion of the apparatus maybe made without departure from the principle and scope of the invention as dened in the following opening for a valve operating connection.
